Explain the title “life on the color line" by gregory howard williams

The title "Life on the Color Line" refers to a metaphorical line that divides the lives of black people from those of white people. In America, these two groups often have very different experiences as they tend to attend different schools, have different income levels, live in different areas, have different hobbies, etc. The book tells the story of a man who considered himself white, but then discovered he was black. Therefore, he was living "on the color line" as he found himself in the middle of these two spheres of life.
